Xenon-133 Shortage Information

A supply shortage of Xe-133 is expected to occur from May 16 to May 29 and is anticipated to be restored to normal supply by May 30.

During this time, the only alternative for performing Xe-133 ventilation imaging is Tc-99m DTPA aerosol imaging. This procedure is described in SNM’s Lung Scintigraphy practice guideline

Tc-99m DTPA aerosol imaging is performed using a commercially available delivery apparatus (insert kit plus shielded box). This can be purchased from the following companies:
